The Meteor™ Manifold System provides a versatile yet economical solution for many hot runner mold designs. Two-drop (in-line) and four-drop (X-style) manifolds are available in sizes to suit a variety of applications. Pre-engineered with accurately machined flowchannels, nozzle ports can be freely located anywhere within each manifold’s flow channellimits. Stocked for quick delivery, Meteor manifolds are supplied with replaceable, press-fittubular heaters. A full complement of ancillary components are also available to completethe system design and construction. Nozzle selection can be made from a broad array of D-M-E nozzles, including the 250 and 375 Series, the popular Mini Gate-Mate™ and theGate-Mate 4™ Series.

SECTION 1
Inspection of the Meteor Manifold and Ordered Components
Prior to system assembly, D-M-E strongly suggests that you complete the followinginspection and establish the procedures that will facilitate proper system assembly.
1. Ensure that all components provided are the correct part number and quantities.
2. Check all the supplied heaters for proper resistance in ohms (Ω) and for insufficientresistance to ground conditions by doing the following:
♦ Measure each corresponding heater’s resistance and determine if they are equivalent.(Insufficient resistance to ground is defined as a reading to ground of 20,000 Ω or less.)

SECTION 1
Modifications to the Meteor Manifold Before Use
The D-M-E Meteor manifold as supplied will require machining for the vertical flow channels(drops) that will allow the plastic to flow out of the manifold into the nozzle assemblies. Thefollowing will assist you in the machining process.
Operational Recommendation
All machining operations must be done without cutting fluids.
1. End Plug Machining Instructions (see Figs. 1-4, page 6)
♦ Determine the correct manifold end plug cutoff dimension. To do this add the 1/2 NLdimension to the correct “Y” dimension plus the correct “C” dimension together. Thensubtract the 1/2 O.A.L. dimension from that number to give you the needed “W” dimension to remove from the manifold end plug. Formulas: 1/2 NL = DL – DL x 0.0000113 x (TPR–TAM) Metric Units
1/2 NL = DL – DL x 0.0000063 x (TPR–TAM) Imperial Units W = (1/2 NL + “Y” + “C”) – 1/2 O.A.L.
“W” is the amount of material to remove from end plug. If 1/2 NL minimum is used for vertical flow channel, no alteration to end plug is required.
♦ Cut end plug to length.
2. End Plug Installation
♦ After the manifold plug has been machined to the correct length install it into the manifold along with the retaining set screw. Each set screw should be torqued to a value of 200 ft-lbs.
3. Machine Vertical Flow Channels
♦ Using the existing dowel locations, set up the manifold block for the machining of thevertical flow channels. Pick up the location of the center dowel. Move to the correct 1/2 NL location then center drill, drill 1mm undersize to the center of the main horizontalflow channel for the 9mm or 12mm diameter vertical flow channel. Then, using a 9mmor 12mm diameter ball cutter, finish machining the full radius into the plug end. Depthfor 9mm diameter flow channel is 27.5mm and depth for 12mm diameter flow channelis 29.0mm. Repeat these steps as necessary for each 1/2 NL location.
4. Clean and Prep
♦ Carefully clean out the manifold flow channels to be sure they are completely free fromall machining debris.
5. Nozzle Seat Installation
♦ Apply anti-seize to the threads, then install the manifold nozzle seat and torque to125 ft-lbs.
Pre-Assembly Design & Inspection Guidelines
DL = Distance from centerline of mold to actual drop location in mold
TPR = Processing temperature (°C/°F)
TAM = Ambient temperature (20°C/68°F)
1/2 NL = Distance from centerline to verticalflow channel in manifold in coldcondition
1/2 NL = DL – Thermal expansion

Application Guidelines
To ensure success of each Meteor application, it is important that the mold designer take thefollowing factors into consideration:
♦ Use the Meteor manifold to establish the shape of the manifold clearance pocket in the manifold retainer plate (see pages 12 and 13).
♦ Selection of proper mold steel for the gate area.♦ Proper machining of the gate detail to the supplied drawing on the packing list
supplied with each nozzle.♦ Proper cooling of the gate area to ensure proper gate vestige and to minimize
the drool or stringing of the material.♦ Adequate cooling in the nozzle plate, manifold retainer plate (used to enclose the
Meteor manifold) and the top clamp plate.♦ Use of proper size and number of assembly screws to support the system
(customer supplied).♦ Allowance for adequate system cold clearance to permit later thermal expansion
(refer to pages 23 and 24).
NOTE: Please treat these suggestions as guidelines only. Always follow standard mold making industry practices to ensure the proper function of the mold and manifold system.

SECTION 3
For optimal performance, the riser pads are to be positioned directly above the nozzlelocations “DL.” The chart above shows the minimum distances from center of mold to riserpad locations to avoid interference with the locating ring. These minimum distances onlyapply to the meteor 100 and 150 series. The 200, 300, 400 and 500 series manifolds shouldhave riser pads located directly above the nozzle positions “DL.” For maximum support, useriser pads ERP2001 or ERP2002 whenever possible. Only use riser pads ERP1011 orERP1012 when there are space constraints.
If “DL” falls below the minimums shown in the chart above, the center support pad can beeliminated, but the locating dowel must always be used.

SECTION 3
Nozzle Plate(customer to supply)
♦ Note the dowel pin locations on your Meteor manifold block and machine SD2 dowellocation into the nozzle plate (see Figs. 14-16, page 14, and table on page 15).
♦ Provide adequate cooling lines around the nozzle locations and under the manifold.
♦ The nozzle plate should be machined from D-M-E #2 steel or equivalent strength mold steel.
♦ Wire channels should be provided to route and protect the wires. These wire channelsshould not be positioned under the manifold. High temperatures in these areas may causedamage to the system wiring. A pocket may be required under the manifold heater leadsto provide adequate clearance. See page 20 for clearance requirements.
Operational Recommendation
The nozzles should be keyed in the nozzle plate to prevent rotation. This willfacilitate the tip removal for replacement or cleaning of foreign material from thenozzle tips if necessary. The preferred method for keying the nozzle is on page 21.
1. Nozzle Measurements
For Gate-Mate 4 front-load heater applications,refer to D-M-E Mold Tooling Technologiescatalog Section P mini print 1800 for machiningand wiring specifications. Check the “A”dimension of the nozzle assemblies to ensurethis dimension is within specification and toestablish a base for all other dimensions.Record the value on the Master InspectionSheet (page 30).
2. Counterbore Depth Measurements
Inspect the nozzle plate that will house thenozzle for flatness. Ensure the wire channelsare free of any sharp corners or burrs. Alldirectional changes should incorporategenerous radii. All of the nozzle headcounterbore depths are to be +.001/-.000 inch to the designed dimension. Measure thecounterbore in three locations to ensureflatness. Record this number as “B” dimensionon the Master Inspection Sheet.

3. Head Height
Install the nozzles into their respective counterbores. DO NOT INSTALL THE SEAL RING AT THIS TIME. Check the height of the nozzle head to the plate in which the nozzles areinstalled. Record these dimensions as “C” on the Master Inspection Sheet (page 30).
Operational Recommendation
Mark the nozzle bodies on their outer diameter with the location in which they willbe installed. Pay particular attention to systems that use different length nozzles. On multi-cavity molds, the marked number will normally reflect the cavity number,which in turn will match the temperature control zone number. Each nozzlecounterbore location should be numbered with its appropriate location. Use themold “O” (OFFSET) corner as a location reference.
Section 4 of this assembly guide contains a typical wiring schematic for the Meteor system. If this schematic does not suit your application you should alter it or draw a new schematic to provide the end user (customer) with this needed information.
4. Grinding Support Pads
♦ If needed, size the manifold center support to a dimension of +.000/-.001 inch to theheight of the nozzle head found in step #3. Grind both sides of the center support pads toensure parallelism.
NOTE: The support pads are manufactured from a non-magnetic material. Fabricate aholding fixture to be used for the grinding of these supports. Record thisdimension where indicated on the Master Inspection Sheet.
Operational Recommendation
In the center of the manifold, center dowel is always required. The center support is not required if the space between the nozzle heads is insufficient.
♦ Properly position the Meteor manifold onto the nozzle plate using the dowel pins. Thedowel pin located in the center will also locate the center support pad. The second dowelshould be positioned at the end of the manifold. The dowel location on each end of theMeteor manifold will be machined as a slot. This will allow for thermal expansion (growth),and will be on the bottom of the manifold. There should be clearance between the top ofthe dowel pin and the bottom of the slot in the manifold. This clearance should be at least.060 inch to ensure that the dowels do not hold the manifold above the nozzles. The useand proper location of these dowel pins is important to ensure the nozzle drop locations are aligned with the nozzle flow channels. Install the dowel pins and check that the heightmeets the above criteria.
20026 Meteor SAG 4/22/05 1:37 PM Page 24

♦ Check the Meteor manifold thickness and record this dimension as “H-1” on the MasterInspection Sheet on page 30. Next, test fit the Meteor manifold block over the nozzles (with seal rings removed) and dowel pins. Making sure that the Meteor manifold lies flatacross the nozzles and center support without any rocking motion.
♦ Establish the “D” dimension by adding the average “C” dimension to the “H-1” manifoldthickness. Record this dimension on the Master Inspection Sheet.
♦ Before installing the manifold retainer plate, check and record the thickness of the retainerplate. Record this dimension as “E” on the Master Inspection Sheet.
♦ Carefully install the manifold retainer plate taking care not to pinch any wiring. Check forproper clearance around the manifold to the manifold retainer plate, and also around themanifold heater termination areas.
NOTE: It may be necessary to machine clearance slots in the manifold retainer plate to clear the nozzle heater leads.
5. Preparing for Final Assembly
♦ Size and install the upper support pads to the underside of the top clamp plate. This dimension will be the difference between the “E” dimension minus the “D” dimension minus the cold clearance (see formula immediately following below). Record this as dimension “SP” on the Master Inspection Sheet.SP=E-D-total cold clearance.
NOTE: Note the upper supports are manufactured from non-magnetic material. Fabricate a holding fixture to be used for the grinding of these supports.
FORMULA FOR FIGURING THE AMOUNT OF THERMAL EXPANSION(Determining the cold clearance value)
“H-1” x .0000113 x (process temp. - 20°C) - .0762 = total cold clearance Metric Units
“H-1” x .0000063 x (process temp. - 68°F) - .003 = total cold clearance Imperial Units
“H-1”= The manifold thickness
♦ Test fit the top clamp plate to check interference between upper support pads and anymanifold components or wiring. Check and record the nozzle “Z” dimension on the MasterInspection Sheet. THIS DIMENSION SHOULD FALL WITHIN 0.001 in. OF EACH OTHER.Remove the top clamp plate and inspect the manifold area. Remove the retainer plate andset it aside temporarily.
♦ Remove the manifold, taking care to protect wiring, and prepare to install seal rings into the heads of the nozzles. Check to see that all nozzles and their locations are properlymarked. Mark all nozzles, manifold power and thermocouple leads to ensure proper connection into the system terminal box. At this time, it is possible to wire the nozzleassemblies to the power and thermocouple connectors. Refer to the Wiring Guidelines provided in this assembly guide (beginning on page 26) for further assistance.

6. Final Assembly
♦ Clean seal ring counterbores, INSTALL SEAL RINGS, and then carefully install themanifold into position without displacing the seal rings from their locations. It is now timeto wire-up the power and thermocouple leads to the proper connectors. Clean and installthe manifold retainer plates. DO NOT PINCH WIRING. Clean and install the top clampplate. Then torque down the bolts that tie the top clamp plate to the nozzle plate usingthe torque values specified on the system design drawing.
♦ Determine the locating ring cutoff dimension “G.” Measure from the surface of thelocating ring flange to the nozzle seat flange on which the drool ring rests. Subtract 0.010in. and record this dimension as “G” on the Master Inspection Sheet on page 30. Machinethe locating ring skirt length to this dimension and counterbore for the drool ring87.88mm/3.46 in. dia. x .006mm/.15 in. deep. Finally, install the drool ring and locatingring onto the top clamp plate.
NOTE: If E-D=14.2mm/.56 in. (refer to Figs. 24 and 25 on page 25) then use D-M-ELocating Ring item #EHL-0256 (no alteration required). Otherwise, use EHL-0255 andalter as specified to “G” and counterbore.
♦ Carefully assemble the top clamp plate to the remainder of the mold.
♦ USE CAUTION to avoid pinching any of the system wiring.
♦ Install all assembly screws and torque down as required.
♦ Recheck all wiring for continuity.
♦ Bench test the unit.

SECTION 4
Operational Recommendation
In the event that multiple zones are ganged together to minimize the requirednumber of control zones, it will be necessary to use one pair of thermocouplewires per ganged set of nozzles. Run other thermocouple leads into the terminalbox, insulating and identifying each for use as spares if required at a later date.
♦ Ground Connection: A ground connection must exist between the Hot Runner system(mold base) and the temperature control system. This is accomplished via the D-M-E mold power cable, which contains a ground wire (green) provided on the connector.
TO PREVENT ELECTRICAL SHOCK AND ENSURE PERSONAL SAFETY, THE GROUNDING WIRE SHOULD BE CONNECTED TO THE MOLD BASE OR THETERMINAL BOX ITSELF.
♦ Power and Thermocouple Connector Placement: Do not place the mold’s power or thermocouple plugs in any area where they will be exposed to extreme temperature or humidity.
♦ Confirm zone numbering with respect to cavity numbers.
♦ Wire Channels: Use wire channels to ensure that wiring for nozzle and manifold (including thermocouples) is routed away from the manifold. Use retainer clips to hold thewiring in the channels to prevent wires from being cut or pinched during final assembly.
♦ Recheck resistances of heaters and thermocouples. Compare to previous results. If values are different, troubleshoot the system. Record these values on the MasterInspection Sheet provided.
♦ Adding Wire to Nozzle Heater Leads: If additional lead length is required, use the same type of wire. Where the connection is made, a non-insulated butt connectorshould be used and taped over with a high-temperature insulating tape. Be sure to test all connections before final assembly.
♦ Adding Wire to Thermocouple Leads: If additional lead length is required, use only type “J” thermocouple wire [positive (+) white, negative (-) red]. The wire should be double-length stripped, folded for proper silver-brazed connection, and taped over with a high-temperature insulating tape.
NOTE: Wiring kits are available from D-M-E.

Instructions Prior to Installation of the Meteor Manifold System
Perform the following checks before installing the Hot Runner System into the press.
1. With the system properly grounded, execute an electrical check of each control zone forboth power and thermocouple connections. Check the heater leads for continuity.The resistance checked to ground of all heater leads must be greater than 20,000 ohms(20 KW).
2. Check each thermocouple circuit for continuity. It is also important to check for continuity between thermocouples and heater elements. There should be no circuitbetween the heater element and the thermocouple.
3. Bench test the unit with the temperature controller set at 149˚C/300˚F. Ensure all heaterscome up to the desired set point. If desired set point is not reached, troubleshoot thesystem.
4. When the mold is installed in the press and all water connections are made, plug thepower and thermocouple cables into the mold terminal box.
5. Set the temperature controller to the correct processing temperature for the materialbeing molded. This value is usually about 10˚C/50˚F higher than front machine barreltemperature setting.
NOTE: Allow all heaters to go through a moisture dryout process (soft start).
6. Bring the system up to the correct processing temperature. Turn on mold water (cooling)and close the mold. Extremely cold water is not necessary. Water temperature of38˚C/100˚F should keep the “A” side of mold from expanding at a different rate than the “B” side of the mold.
7. When the Hot Runner System has reached set point and is normalized, the D-M-Etemperature controllers will show a green light in the center of the deviation light display.
8. Make sure that the machine nozzle orifice is as large as, but not larger than, the nozzleseat flow channel. This will allow maximum throughput to the Hot Runner System andthe mold cavities.
9. Be certain that the nozzle radius on the machine barrel matches the nozzle seat radiuson the manifold to prevent drooling. This should ensure a leak-proof seal.
10. Purge the barrel to ensure stable material enters the manifold.
11. Move the machine nozzle into position against the manifold nozzle seat.

Meteor Manifold Start-Up Procedures1. Ensure that the machine’s nozzle tip is properly seated on the manifold nozzle seat.2. Set machine back pressure to 300-500 psi.3. Run the extruder until material flows through all nozzle orifices (gates). Run for an
additional 5-15 seconds. Then clear gates and all mold surfaces of material. If the material nozzle will not stay against the tool, see Notes and General Comments (below).
4. Move the sled back and decrease back pressure to normal setting.5. Set decompression/suck back at a minimum 0.500 in. to control drool.6. Set molding parameters.7. Move sled forward.8. Start the molding process.9. Check the system for leaks.
Notes and General CommentsIf the system will not start up, throttle down or shut off water to the “A” plate. Water to thenozzle plate should remain on.
If the machine will not extrude with the tool open, close the tool, jog the screw forward, open the tool, close the tool, and jog the screw forward again.
If the machine nozzle will not stay against nozzle seat, PROCEED WITH CAUTION. Setinjection forward pressure to 200 psi. Set injection speed to slow, making sure the system is up to temperature. Move the sled into the tool and cautiously jog injection forward until material flows through gates. If necessary, raise the injection pressure in steps up to, but not exceeding, 500 psi. Clear gates and all mold surfaces of material. Finally, start the molding process.
NOTE: NEVER inject plastic through the hot runner system with the mold open.
CAUTIONS♦ Make sure you wear proper safety equipment such as gloves and face shield at all times.
♦ Never use a torch to open frozen-off gates. This may damage tips, gate detail, or the mold itself.
♦ If you insert anything into the gate or tip to clear it, you must first back the machine nozzle away from the tool. Check for drool out the back of the manifold before you start.Drool here will indicate little or no pressure in the manifold.
♦ Never inject any Hot Runner System with high injection pressure when the mold is open.
♦ During the first 15 minutes of operation, check system for leaks. Loss of shot size could be an indication of leakage.
♦ Check to see that all cooling fans are operating in temperature-control main frames.
♦ Input voltage to the main frame system must not be less than 208 VAC.
♦ Voltages less than 240 VAC will require an extended time to bring the system up to its proper operating temperature. Lower voltages decrease effective wattage. For example: at 208 VAC, the effective wattage is 28% less than that at 240 VAC.
